Craig Rounsefell B.Comm

Managing Director – Boomer Bloodstock Pty. Ltd
President – Boomer Bloodstock Corp.

Craig’s passion with the racehorse and the thoroughbred industry started at a very early age and has culminated with him starting his own bloodstock agency, Boomer Bloodstock International, on returning to Australia in December 2008.

Prior to the commencement of Boomer Bloodstock International, Craig worked in the USA. He undertook an internship with Keeneland Association in Kentucky during 2007, taking in the September Yearling Sale, October race meet, November Breeding Stock Sale, January mixed sale and the inspections for the two year old breeze up sale. Following his time at Keeneland, he moved to California and worked as an Assistant to American Hall of Fame Trainer, Neil Drysdale for the 2008 racing season at Hollywood Park, Santa Anita and Del Mar racetracks.

In 2005, Craig was selected onto the prestigious Darley Flying Start International Student Program sponsored by Sheikh Mohammed bin Rashid Al Maktoum, and spent the next two years working on racing and breeding operations throughout Ireland, England, America, Japan, Australia and Dubai. During this time, he also undertook work experience with William Inglis and Son in Australia, BBA-Ireland, Charlie Gordon-Watson in the UK, Mike de Kock Racing Stable in Dubai and Darley Japan. Craig graduated from the Program in July 2007 in First Position.

In 2003 and 2004, Craig worked for Champion Australian horse trainer Gai Waterhouse as part of her team at all the major thoroughbred sales in Australia and New Zealand, working closely with renowned Australian thoroughbred judge George Smith. Following his graduation with a Bachelor of Commerce Degree from the University of Queensland at the end of 2004, he moved to Sydney and worked full-time for the Gai Waterhouse Racing Stables.

In 2001, Craig spent twelve months in the UK working as a sports coach at The Duke of York’s Royal Military School in Kent. During the holidays throughout the year, he had the opportunity of working for John Oxx at his Curraghbeg Stables on the Curragh in Ireland.

In his earlier years, Craig spent the majority of his spare time with Terry Catip (long time foreman to legendary Australian trainer TJ Smith) on his horse property near Warwick, Queensland, learning as much as he could about the thoroughbred which laid the foundation for his future endeavours.

Boomer Bloodstock Pty. Ltd. is a member of the Federation of Bloodstock Agents Australia Ltd and is bound by a strict code of conduct and code of ethics.

In 2016 Craig was appointed by Australian auction house William Inglis & Son, as their North American representative.

Lynn Hancock

Bloodstock Liaison

Born and raised in Paris, Kentucky, Lynn’s deep love of all things thoroughbred is ingrained in her pedigree and dates back five generations.  Having grown up on Stone Farm, Lynn has been fortunate enough to learn about all aspects of the horse industry from her father, Arthur B. Hancock III, founder of Stone Farm. Since its inception in 1970 Stone Farm has established itself internationally as one of the leading thoroughbred operations in North America, producing six champions and three Kentucky Derby winners in Gato Del Sol, Sunday Silence, and Fusaichi Pegasus.  Lynn’s grandfather Arthur (Bull) Hancock Jr. was one of the most influential people in thoroughbred history standing many champion stallions at his Claiborne Farm.


Lynn graduated from Sewanee, The University of the South in 2009 with a BA in Art History, and went on to pursue a career in interior design.  After five years working in Los Angeles and New York, it was her love of the horse industry that pulled her back to her home state of Kentucky in 2014. Since returning, Lynn has worked both the yearling and breeding stock sale consignments for Stone Farm, and is a Horse Country Committee Member.  A licensed equine and property insurance agent, she has spent the past two years with Stone Agency.

McCall Rounsefell

Administrative Assistant

McCall hails from a rich history of horse racing in North America dating back to her grandfather, Earl Mitchell, who trained successfully in California during the 50’s and 60’s for owners such as Lucille Ball and Desi Arnaz. McCall was very fortunate to spend many of her early years working alongside her late father Mike Mitchell, one of the all-time great trainers in North America with 21 training titles, 2690 wins, and $67 million in prize money.

During this time, McCall competed successfully in hunter jumpers and was also privileged to spend time in the company of other legendary trainers, Charlie Whittingham, Bobby Frankel and Willard Proctor, which furthered her knowledge of the thoroughbred and training racehorses. McCall went on to pursue her other great passion, the arts, and completed her Associate Degree at FIDM in Los Angeles, graduating in 2005. Since marrying Craig in 2009, McCall has continued her interest in the thoroughbred business attending various sales and race meetings through Australia and North America and is the Administrative Assistant at Boomer Bloodstock International.
